TEX/TILE WINDING MACHINE Filed Aug- 6, 1929 3 Sheets-Sheet' 3 channels or grooves 28 and said jaws being further bifurcated to straddle the body 21, whereby the furcations 24 which lie on opposite sides of the body are slotted as at 25 to receive therethrough the bolts 26. This permits of the proper setting of the jaws to correspond with the width of the reels or cores which are being used. The elements further include a pair of relatively movable gripping jaws 27 which are designed to engage with and grip the opposite faces of the reels or cores. The gripping jaws 27 are provided with threaded apertures 28, the threads of the aperture of one jaw being oppositely pitched to the threads of the aperture of the other jaw for engagement with the oppositely pitched threaded portions 29 of an adjusting screw which is journaled in the central web 30 of the body 21, it being understood that the adjusting screw is provided with a central annular groove 81 withinywhich the retaining screw 32 engages.

The opposite extremities of the adjusting screw are provided with manipulating handles 33, by virtue of which the adjustment of the jaws may be readily accomplished. AThe core engaging head 18 is provided with a hub 35which is keyed to a driving shaft 86 operatively Yconnected with the driving mechamsm, while the remaining elements 17, 19

and 2() are each provided with a hub 37 within which an anti-friction bearing 38 is arranged to receive a trunnion 89. The trunnion 39 of the element 17 is secured tothe end frame member 11, while the trunnions 39 elements .19 and 2O are axially slidable in spaced ears 41and 42 at the opposite ends of an" arm 43. Each stub shaft 40 has secured thereto a collar 4, against which yone terminal of a coiled expansion spring 44 engages with its opposite terminal abutting the ear 42 to normally effect movement of the stub shaft inwardly until the collar 4 abuts the ear 41. Thiscauses the elements 19 and 20 to be normally moved a limited distance toward the corresponiding elements 17 and 18 and atthe same time tensions the elements 19 and 20 against movement in an opposite direction. The arm 43 is provided with a. central hub 45 which receives the inten' and 20 will be spaced from the elements 17 Y and 18 a. distance slightly less than the lengths*` of the cores or reels being used, whereby the cores or reels may be associated with the elements 17 and 19 and 18 and 2O by compressing the springs 44 so that the tension of the springs serves to maintain the cores or reels in position between the clamping and gripping jaws 22 and 27. In order to maintain the arm 43 in itsl shifted position, a set screw 49 extends through Vthe hub 45 Aand is adapted to' be Vmanipulated for frictionally engaging the cross rod 14. It will be observed that the arm 43 is substantially il-shaped with the free extremities projecting forwardly and disposed in superposed relation so that the bolt reel to be unwound and the core upon which the cloth is to be rewound are disposed in close proximity to each other and in vertically spaced relation' at the forward side of the machine, to facilitate the application of the bolts to the core or reel. engaging elements and the Ythreading of the cloth through and the removal of the rewound bolt from the machine without the necessity of the operatorhaving to walk from one side of the machine to the other. l

A measuring roll 50 is journaled in the end members 10 and 11 and is suitably connected with a measuring device `51 supported by the end member 11. The measuring roll is disposed at the uppeiend of the bowed upper portions 16 of the end members 10 and 11 and a pressure roller 52 cooperates therewith to maintain the cloth in contact with the periphery thereof. .A guide blade 54 is supported by the cross rod 15 and is especially designed for engagement between the folds of a folded cloth so that its terminal engages with the bight to cause the cloth to run straight and to maintain the same crease.

'This guide blade vis supported by a bracket 55 having a hub 55 which surrounds the 4cross 4it being understood that the receiving core is placed in the core engaging elements 18 and 20. The receiving core is rotated by the drive shaft 86 which imparts motion to the element 18. 7 y

in view of the fact that the iiat cores or reels upon which the 'cloth is usually wound have a tendency to cause the cloth to jump and jerk,l equalizing rollers for compensating for the slack caused by the flat winding are employed, and said equalizing rollers 60 and 61 are mounted respectively at points to enthe cloth Vwhere it leaves the bolt to be unwound and where the cloth arrivesl a proximately at the rewinding point. T e

supporting elements; and a carrier in which said latter core supporting elements are journaled, said carrier being mounted for lateral adjustment on a cross connection between the' frame members, said adjustable core supporting elements being journaled in said carrier and normally urged axially toward and tensioned against movement away from the xed rotary driven and idler core supporting elements and said core supporting elements fashioned to embracingly engage with the opposite ends of the cores and including relatively adjustable core side engaging means andl relatively adjustable core side edge engaging means, the former consisting of a pair of clamping jaws and threaded means for advancing the same toward and away from each other to accommodate cores of different thicknesses. Y

6. In a textile rewinding machine, a main supporting frame including vertically disposed transversely spaced parallel frame membersand cross connections therebetween; a pair of superposed fixed rotary driven and idler core supporting elements journaled in one of said frame members and a pair of superposed cooperative adjustable rotary core supporting elements; and a carrier in which saidlatter core supporting elements are journaled, said carrier being mounted for lateral adjustment on a cross connection between the frame members, said adjustable core supporting elements being journaled in said carrier and normally urged axially toward and tensioned against movement away from the fixed rotary driven and idler core supporting elements and said core supporting elements fashioned to embracingly engage witli the opposite ends of the cores and including relatively adjustable core side engaging means and relatively adjustable core side edge engaging means, the former consisting of a pair of clamping jaws and threaded means for advancing the same toward and away from each other to'accommodate cores of differentthicknesses and the latter consist-v ing of a pair ofjaws having confronting grooved faces and means mounting the same for adjustment toward and away from each other to accommodate cores of different width.
